mystery illness

i am 38 years old. 2 months ago, i started having "lightning bolt" pains near my knee cap. it then started near my ankle, then my wrist, next my elbow. they are sharp, dagger-like pains that only last for 5 seconds or less. i say near my joint because it doesn't exactly go directly thru the joint, but rather, off to the side of the joint. hope this makes some sense to someone.

a month ago, my jaw started to hurt and it hasn't stopped. the head pain started 2 weeks ago and that has yet to subside either. i have had numbness in my hands & feet for a year & i'm getting use to that, but now know that it may have something to do with my illness. i started having bladder issues 2 months ago & will be having an interstitial cystitis test next week to determine if i have IC. i read that IC can be associated with FM. doctors can't figure out what is going on. as i said, i had a brain mri & it shows nothing but maybe some irritation within the sinus cavity, of which they do not believe has anything to do with the pain in my jaw/head. they put me on nerve pain med (usually perscribed for those with seizures) & it has helped some - i don't have as much joint pain. do have some muscle pain too, that also just lasts a few seconds : (

i need help. i don't know where to turn. can't get into the neurologist til February. had my eyes examined last week & everything is fine there. do i have fibromyalgia? doctor says no since he did a quick tender point check on right side of shoulder, upper back, and lower back. does anyone know what is happening here?
